In a groundbreaking development, Bristol Myers Squibb (BMY) recently announced promising results for their cancer pill, Krazati, in the treatment of a certain type of non-small cell lung cancer. The company revealed that Krazati not only helped patients live longer without disease progression but also showed higher tumor shrinkage rates compared to chemotherapy. These findings could potentially lead to Krazati receiving full clearance from the Food and Drug Administration (FDA), offering a competitive edge over rival drugs like Amgen’s Lumakras.
Targeting a Common Mutation
Both Krazati and Lumakras are designed to target tumors harboring mutations in the KRAS gene, which are prevalent in non-small cell lung cancer. KRAS mutations are associated with a poorer prognosis, making them a critical target for drug development. For years, drugmakers struggled to develop effective therapies targeting KRAS mutations, often considering them “undruggable.” However, the landscape changed with the rapid development of Lumakras by Amgen, followed by Krazati.
KRAS Mutations
KRAS mutated cancers are a subset of cancer types characterized by alterations in a gene called KRAS. KRAS is a proto-oncogene, meaning it has the potential to promote cancer development when mutated. The KRAS gene encodes a protein that is involved in cell signaling pathways regulating cell growth, proliferation, and differentiation.
Mutations in the KRAS gene lead to the production of a mutated KRAS protein that is constitutively active, meaning it is constantly “turned on” even in the absence of external signals that would normally regulate its activity. This persistent activation of KRAS signaling pathways can drive uncontrolled cell growth and proliferation, contributing to the development and progression of cancer.
KRAS mutations are commonly found in various types of cancer, including but not limited to:
- Colorectal cancer (CRC)
- Lung cancer (especially non-small cell lung cancer, or NSCLC)
- Pancreatic cancer
- Ovarian cancer
- Endometrial cancer
- Thyroid cancer
The presence of KRAS mutations in these cancers can have implications for prognosis and treatment. For example, KRAS mutations in colorectal cancer are associated with resistance to certain targeted therapies, such as anti-EGFR (epidermal growth factor receptor) antibodies. Researchers and pharmaceutical companies are actively working on developing new therapies targeting KRAS-mutant cancers to improve treatment outcomes for patients.
Market Dynamics
Despite the significance of targeting KRAS mutations, the uptake of these drugs has been modest. Amgen reported slight declines in Lumakras sales, while Krazati, initially developed by Mirati Therapeutics, reported relatively low sales figures. However, Bristol Myers’ acquisition of Mirati reflects a strategic move to capitalize on the potential of Krazati.
Clinical Trial Success
Under Mirati, Krazati received conditional FDA approval based on its performance in clinical trials. The drug demonstrated partial remissions in a significant percentage of patients who had previously undergone chemotherapy and immunotherapy. The recent KRYSTAL-12 trial compared Krazati to docetaxel in over 400 patients, with preliminary results indicating Krazati’s superiority in improving progression-free survival and response rates.
Regulatory Pathway and Future Prospects
Bristol Myers has submitted an application to the FDA to expand the use of Krazati in combination with chemotherapy for KRAS-mutated colorectal cancer. The decision deadline is approaching in June 2024, signaling a crucial milestone in the drug’s regulatory journey. While the trial results may not significantly expand the patient population eligible for Krazati, they hold the potential to instill confidence in its efficacy and safety profile among regulators and physicians.
